Fiction Q&A Question 2

Question 2: Is a stylistically altered account of a real event fictional?

From all the conceptualizations of fiction that I have read and encountered include some form of falsity. The events of the narrative must be, to at least some degree representational of things that did not happen. My question is at what degree of separation from reality is an account said to be fictional? I would be tempted to claim that even the slightest alteration would render it false and therefore fictional. However, just stylistic renderings, poetic language and advanced diction, do not render such things fictional, although I admit it may be difficult to effectively use such language and remain completely true to the facts.
